  • RFID radio frequency identification device
  • Fig I it typically show multiple operations multiple-machines manufacturing setup.
  • Machines are arranged in form of cells. Operations and cells are numbered as per sequence of operation. Illustration showed in fig. I shown three operations. First operation is termed as Operation (OP 10), second operation is termed as Operation (OP20) & third operation is termed as Operation (OP 30). Individual group of operations is termed as Object (1). Said object (1) forms a cell for operation. All these cells are interconnected by material carrying conveyor termed as Object (5).
  • Cross gantry (2) is used to transfer the components from conveyor to the machines.
  • Component is picked from conveyor by gantry head and dropped on the machine. Every component is picked up from the component pick up point.
  • Gantry head shuttles between components pick up point to all machines in the cell.
  • Gantry (2) movement is controlled by Gantry Controller (3).
  • Machine controllers give signal to gantry controller for loading the fresh component after finishing earlier component.
  • the Gantry controller loads the component on a machine as per the sequence of completion of process by the machine.
  • Reading devices (4) are mounted on each of the machines in cell. This is communication device to read unique identification code written on component.
  • Central Server (6) is interfaced with all said reading devices (4) and machines. Component tracking information from readers (4) and machine controller is collected in the computer.
  • the main object of this invention is to provide a component tracking system with minimum complexity by using least number of reading and writing devices.
  • Yet another object of this invention is to provide a component tracking system which is easy to maintenance.
  • Another object of this invention is to provide a component tracking system which is simple in construction and cost effective.
  • Component tracking system comprises of at least one machine cell, one or more gantries, gantry controller /s, material handling system, component reader/s, central server, wherein operation wise said machine cells are interconnected by material handling system, said gantry is interfaced to gantry controller and machine controller, said component reader/s is mounted on said material handling system and is interfaced to gantry controller, all said gantry controllers are interfaced with central server.
  • Component tracking system wherein said component reader/s is mounted on said material handling system at pick up points.
  • Component tracking system wherein said material handling system is a conveyor.
  • Component tracking system wherein said machine cell comprises of one or more machines with unique identification for each of said machines.
  • Component tracking system wherein said unique identification of machine is done by either physical co-ordinate on horizontal axis of gantry or by digital code of a machine.
  • Component tracking system wherein said component reader is selected based on format of unique identification mark of component.
  • Component tracking system in accordance with this invention basically comprises of machine cells, one or more gantries and their controllers, conveyor, component readers, central server, wherein operation wise machine cells are interconnected by martial handling conveyor.
  • Said one or more gantry is connected to gantry controller and machine controller, said component reader/s is mounted on conveyor at pick up points and is interfaced to gantry controller, all said gantry controllers are interfaced to central server.
  • Gantry head picks up the material to be processed from conveyor and carries it to the machine and carries it back to conveyor from machine after processing. Movement of gantry is controlled by gantry controller.
  • Said component reader/s reads the components on conveyor only. Information of component reading on a conveyor at pick up points is transferred to server through gantry controller because of which component can be traced by retrieving information from server.
  • This system identifies / read component at pick up point only. This information is transferred to gantry controller. Component picked up is assigned by gantry controller to a specific machine. These machine number and component numbers are linked together and transferred to central server along with details like time and date. This information can be used to track the component. This system reduces number of readers and network connection. Also makes track system less expansive and less complicated.
  • Fig. I shows schematic representation of a conventional component tracing system with component readers on each machine and network connecting to each of the machine.
  • Fig. II shows schematic representation of component tracking system in accordance with this invention.
  • Component reader fitted on the pick up point of the conveyor.
  • Operation- wise cells (1) are interconnected by material transfer mechanisms such as conveyor (2). Components being processed are picked up from loading position of conveyor and dropped on unloading position on conveyor after processing. After component is picked up by gantry head, the gantry controller (3) communicates with the machines in the said cell/s to find out which machine is ready to accept the component for processing. Gantry controller (3) identifies the machine by coordinates on horizontal axis of gantry and component is transferred to the identified machine. The coordinates / address of machines are stored in the gantry controller (3). The address / coordinate are unique for individual machines. The address is linked to unique identification code of the component read by component reader (4) which is mounted on said conveyor (5). The linkage is captured from the gantry controller and used to trace back the origin of each component through central server (6) like the machines on which the particular component has been processed.
  • Method of tracking components by capturing information /sequence is as mentioned below a) Putting unique identification mark on the component by punching or laser marking in the form of 2D - matrix or bar code; b) Putting components on conveyor; c) Reading unique identification mark at pick up points; d) Transferring information of identification mark to the gantry controller; e) Assigning component to a particular machine; f) Transferring identified component to the assigned machine; g) Assigning the information of steps (d) and (e); h) Transferring information obtained from step(g) to central server; i) Information from central server is used to trace the origin of the component.
  • the component tracking system requires reader only at pick point of each gantry / cell, communication port on only gantry controller.

Abstract

Cette invention concerne un système et un procédé associé de suivi de composants. Le système de suivi de composants est constitué par des cellules de machine (1), un ou plusieurs portiques et leurs dispositifs de commande (3), un convoyeur (5), des lecteurs de composant (4), un serveur central (6), les cellules de machine destinées au fonctionnement (1) étant interconnectées par un convoyeur de manipulation de matériau (2). Ledit ou lesdits portiques sont connectés à un dispositif de commande de portique (3) et à un dispositif de commande de machine, ledit ou lesdits lecteurs de composant (4) sont montés sur un convoyeur (5) en des points de saisie et sont en interface avec un dispositif de commande de portique (3) et tous lesdits dispositifs de commande de portique (3) sont en interface avec le serveur central (6). Une tête de portique saisit le matériau devant être traité à partir du convoyeur (2) et porte celui-ci vers la machine, puis le ramène au convoyeur (2) à partir de la machine après le traitement. Le déplacement du portique est commandé par un dispositif de commande de portique (3). Ledit ou lesdits lecteurs de composant (4) lisent les composants sur le convoyeur uniquement. Des informations de lecture de composant sur un convoyeur (5) en des points de saisie sont transférées au serveur par l'intermédiaire du dispositif de commande de portique (3), ce par quoi un composant peut être tracé par récupération des informations à partir du serveur.
